A gerotor pump arrangement for extracting hydraulic fluid from a transmission housing of a transmission. A first gerotor set has a first inner rotor and a first outer rotor, and a second gerotor set has a second inner rotor and a second outer rotor. The first gerotor set forms a hydraulically drivable drive side of the gerotor pump arrangement, and the second gerotor set forms a pump side, driven by the first gerotor set, wherein the first and second inner rotors are rotationally fixedly mounted on a common shaft which is rotatable about a rotational axis. A transmission with such a gerotor pump arrangement is also disclosed.

A gear assembly comprises an axle defining an axis of rotation, a gear mounted to the axle for rotation relative to the axle about the axis of rotation, a pin, and a thrust washer disposed axially adjacent to the gear. The pin is disposed in a portion of the thrust washer and extends into the axle.

A corn head row unit gearbox includes an input shaft, that rotates about a first axis of rotation and that drives a set of bevel gears. The bevel gears transfer rotation of the input shaft into rotation of a set of gathering chain output shafts about a second axis of rotation, generally transverse to the first axis of rotation. The gathering chain drive shafts each rotate within a bushing mounted within a frame structure of the gearbox. The frame structure defines a bore that communicates with a bevel gear cavity, in which at least one of the sets of bevel gears rotates, and an interior of the bushings mounted on the gathering chain drive shafts. Rotation of the bevel gears carries lubricant to an inlet aperture on the bore and drives the lubricant through the bore into the bushings.
